Are these PARAMETERS good enough for LPS/SOFTIES tank?

[Ocean’s Piece]

My tank is a little more than 3 1/2 months old. I haven't put any corals or fish in there yet. Why you may ask. Long story short, I didn't have a good place to put it and when we eventually made space for it about 2 weeks ago, we had to move it. I'm about to start stocking but before, I just want to check if these parameters are fine....
Calcium: 320 (Red Sea)
Alkalinity: 7.8 (Red Sea)
Magnesium: 1300 (Red Sea)
pH: 8.2 (API)
I'm mainly wondering if calcium and alkalinity are fine or if I'm going to have to start dosing when I put the corals in. I'm planning on having about 90% LPS, 10% softies, and maybe later on 5% SPS although highly unlikely.
Any feedback is helpful!

These are ok

Calcium: 320 (Red Sea) this I'd raise to about 400-420 ppm for Lps.

What about No3 and Po4 for corals? Should not be zero.

They aren’t. Nitrate is about 5 ppm and Phosphate around .15. Feeding fish food to maintain these levels to prevent Dinos. Not worried about these as much as the 4 above.

I find my LPS extend better with elevated magnesium, I run 1410-1450ppm, even 1500.

Calcium is too low at 330 ppm. I recommend 380-500+ ppm.
